HIGH-G TELEMETRY SYSTEM FOR TANK MUNITIONS

摘要

The High-G Telemetry System for Tank Munitions was designed for and used on the Tank Projectile Course Correction Project, which is a program to design, develop, manufacture, assemble and deliver a course correction system, for a 120mm projectile by increasing the probability of hit against stationary and moving targets. The Precision Munitions Instrumentation Division (PMID) of U.S. Army TACOM-ARDEC has been providing high "G" telemetry services for over 50 years. Some of the capabilities of the group involve design, development, fabrication, testing, and data acquisition and analysis. The Precision Munitions Instrumentation Division is supporting this program by designing and manufacturing a telemetry system for monitoring on-board divert mechanism operation and sensors during the gun launch and in-flight. The telemetry system that was designed for this effort was a six channel voltage controlled oscillator (VCO) FM/FM (frequency modulation) telemetry system. It was designed as a modular system that included a battery module, a multiplexer module, and a transmitter module. The system interfaced with a contractor's electronics modules through a set of 15-pin MDM connectors. The telemetry package was integrated into a 120mm tank round and fired at approximately 50Kg's. The telemeters were 100% successful in surviving the gun launch and collecting live flight data. Data transmitted by the telemeter included on-board sensor suite data, processor data, power levels, and others. The maximum frequency response of the system is 50 KHz, in order to transmit the processor's digital data.
